Definitions
- the present invention is concerned about a card flat for a carding machine.
- One of main component in the process of carding is card flat and its pattern of arranging the Wires of flats which contributes a significant role in carding functions.
- the invention relates to direction of flat wires of card flat. More particularly, the invention relates improved flats with wires for a carding machine.
- Spinning process of yarn involves cleaning and removing of impurities present in the fibre, aligning i.e. parallelizing of fibres and men spinning of fibre strands in a yarn.
- the cleaning and aligning of fibres are mainly done on the first two process machineries Le. Blow room and carding machines.
- Carding process involves extensive cleaning of impurities in the fibre mixing and separation of fibres to individual level.
- main carding action takes place between the roller called carding cylinder which is clothed with wire teeth of various size and shapes according to requirements and flats clothed with either with wire or saw teeth.
- These rollers and bars also work at a very close proximity arid with different surface speed.
- a carding machine is illustrated in the drawing.
- the main working roller and bars are mentioned in the figure 1.
- the carding machine mainly has three rollers known as Licker in 1, Main Cylinder 2, Doffer shown in drawing.
- the flat bars are clothed with Flat top shown in the drawing on enlarged scale and known as "revolving flat".
- the flat tops comprise of a flexible foundation on which wire staples of different type of cross section i.e. elliptical, ovoid or flat are pressed in.
- the end of the wire projecting from flexible foundation is bent in the intended direction so that it is opposite to that on main cylinder of motion of the revolving flats.
- the tip of the wire is ground on the top as well as sides to create a sharp wire points.
- These flat tops are mounted on the flat bars known as "bare flats".
- the revolving flats covered with fine wire points of flat tops.
- the relative direction of wire points on different components particularly rollers are provided on the basis of the action between two set of wire points. As shown in Fig 1 the direction of wire points in licker in and Cylinder are same. Hence it performs stripping action.
- the wire points in Main Cylinder and flat tops are opposite. Hence it performs carding action.
- the cylinder should rotate at high speed i .e. with a high surface speed while the revolving flats move at a lower surface speed.
- the transfer of fibre from Licker in to cylinder depends on various factors e.g. the angle of wire points, relative surface speed of the two components and most importantly the gap/gauge between the two clothed surfaces.
- the evenness of the gap between cylinder and licker in 6, between cylinder and flat tops 5 and between cylinder and doffer 7 are Very crucial and important to achieve good and consistent performance from a carding machine.
- One of main objects of this invention is to remove above mentioned drawbacks. Further object is to change the direction the wires of flat clothing as required so that even carding is carried out.
- Another object is uniformly maintaining carding action
- a carding machine comprising:
- traveling flats cooperating with said main carding cylinder along a circumferential length portion thereof; said traveling flats including
- said plurality of flat bars each having different direction of heiix of clothing being placed alternatively to deflect the fibres from one direction to another direction
- the principal work of the carding machine is to separate individual fiber which is carried out between the main cylinder and the fiats. Only by means of this fiber separation, it is possible to eliminate the fine dirt particles and dust.
- the improved pattern of wiring of fiat tops is in the direction is from left to right direction Conventional system :
- Each carding Machine will have 80-110 Numbers of revolving Fiat Tops according to the construction of the carding machine
- the wire points in the flattops are planted in a manner to create a canal like flow path so that the individualized fibres will follow that path. Normally any material flow will try to take the easiest path to flow easily.
- the Canal path is diverted to opposite direction - say left helix in the next top coming into action by re arranging the pins in this second top.
- the fibre flow is disturbed/ twisted and facilitates further combing. It is expected that fibre bunch will get loosened and split into many paths. Again the third top will be coming into action to divert fibre flow with right helix direction. This diversion will continuously happen during carding process.in such a manner that fibres are deflected from one direction to another direction during carding. The fibres are deflected from at least one flat to next flat due to change in helix pattern of clothing.
- the direction of fibres is changed from a plurality of flats tops to plurality of flat tops with different helix preferably two flats with one direction of helix are placed after two flats with different direction of helix on the fiat tops so that flow of fibres is changed after each two flats
- the helix angle of wires clothing is varied between 0 degree and 89 degees helix provided in flat clothing either with saw teethed flat tops or with flat wires.
- Fig 1 shows the schematic side view of the carding machine shown with the detailed components
- Fig 2 shows the plan view of conventional unidirectional pattern of flattops
- Fig 3 shows the plan view of proposed improved alternatively arranged flats with two directional flattops
- Fig 4 shows the detailed arrangement of flat in combination with carding cylinder
- Fig S shows the flat tops with right helix direction
- Fig 6 shows the flat tops with right helix.
- like reference numbers are used to depict the same or similar elements, features, and structures.
- fig 1 Carding process involves extensive cleaning of impurities in the fibre mixing and separation of fibres to individual level. To facilitate separation of fibres to almost individual level the rollers and bars in the carding machine are clothed with clothing which comprises of wire teeth of various size and shapes according to requirements. These rollers and bars also work at a very close proximity and with different surface speed.
- a schematic side view of carding machine is illustrated in Fig 1. The main working roller and bars are shown in the figure 5. There is an enlarged view of the revolving flat in fig 5.
- the carding machine mainly has three rollers known as Licker in 1, Main Cylinder 2, Doffer 4 shown in fig 1.
- the ilat bars are clothed with flexible wires made of steel 3 shown in fig 5 on enlarged scale and known as "revolving fiat".
- the fiat tops comprises of a flexible foundation on which wire staples of different type of cross section i.e. elliptical, ovoid or flat are pressed in. The end of the wire projecting from flexible foundation is bent in the intended direction so that it is opposite to that on main cylinder of motion of the revolving flats.
- the tip of the wire is ground on the top as well as sides to create a sharp wire points.
- These flat tops are mounted on the flat bars known as "bare flats".
- the Fiat bar is clipped with metallic top i.e. saw tooth wire instead of flexible wire.
- the relative direction of wire points on different components particularly rollers are provided on the basis of the action between two set of wire points. As shown in Fig 1 the direction of wire points in licker in and Cylinder are same. Hence it performs stripping action.
- the wire points in Main Cylinder and flat tops are opposite. Hence it performs carding action.
- the cylinder should rotate at high speed i.e.

Abstract
L'invention concerne une machine à carder qui comprend un cylindre à tambour principal comprenant un axe de cylindre et portant une garniture de tambour sur sa surface circonférentielle ; ladite garniture de tambour comprenant des pointes de garniture. Les chapeaux tournants améliorés ayant des hélices différentes coopèrent avec ledit cylindre à tambour principal le long d'une partie de longueur circonférentielle de celui-ci. Une pluralité de barres de chapeau ayant une garniture souple avec soit une scie, soit un fil coopérant avec ladite garniture de tambour en dents de scie. L'amélioration consiste en ladite pluralité de barres de chapeau ayant différentes directions d'hélice de garniture qui sont placées avec une séquence différente pour dévier les fibres d'une direction vers une autre direction pour une meilleure action de cardage.
